Hi there,
I have a question about the replica and replication factor.
For example, I have a cluster of 6 nodes in the same data center.
Replication factor RF is set to 3 and the consistency level is default 1.
According to this calculator http://www.ecyrd.com/cassandracalculator/, every
node will store 50% of the data.
When I want to read all data from the cluster, how many nodes should I read
from, 2 or 1? Is it 2, because each node has half data? But in the calculator
it show 1: You are really reading from 1 node every time.
Any suggestions? Thanks!
